9/11: A tribute in light

The ‘Tribute in Light’ shines as One World Trade Center (L) rises under construction on the eleventh anniversary of the terrorist attacks on lower Manhattan at the World Trade Center on September 11, 2012 in New York City. New York City and the nation are commemorating the eleventh anniversary of the September 11, 2001 attacks which resulted in the deaths of nearly 3,000 people after two hijacked planes crashed into the World Trade Center, one into the Pentagon in Arlington, Virginia and one crash landed in Shanksville, Pennsylvania.
